TRANSMISSION OPERATION CHARACTERISTICS
MechanismOperation characteristics
Base Manual transmission
.The GT-R transmission design is different from transmissions used in conventional passenger cars. The GT-R uses a transmission gear
design, light flywheel and a dry sump lubrication system to provide maximum vehicle performance. Because the GT-R Transmission design
is different, noises may be louder. When the transmission temperature is high, rattling, shaking and jarring noises may be heard.
.Clattering noises may be heard while shifting..Appropriate gaps are provided between gears to achieve smooth gear rotation and steady tooth surface lubrication under the high-load
driving condition. However, this causes a rattling noise.
.If the shift lever is moved from&Rto&A↔&Mposition, or&A↔&Mto&Rposition before the vehicle stops, you may not be able to shift gear
or it may take longer to shift gear. Make sure to depress the brake pedal and check that the vehicle has stopped before shifting.
Multiple disc wet clutch
.When stopping the vehicle with the shift lever in the&Ror&A↔&Mposition, be sure to firmly depress the brake pedal. The vehicle may
slowly move if the brake pedal is not depressed.
.Avoid depressing the brake and accelerator pedals at the same time. Depressing the brake and accelerator pedals at the same time could
cause the clutch to overheat and accelerate deterioration.
.When the vehicle is stopped on a hill, do not hold the vehicle in place by depressing the accelerator pedal. Doing so may cause the clutch
to overheat and result in transmission damage. Use the brakes to prevent the vehicle from moving.
Electronic oil pressure
control The following conditions are caused due to changes in fluid viscosity as a result of temperature changes.
.When the transmission oil is extremely cold or extremely hot, the transmission may feel like it is slipping during shifts or there may be hard
shifts. This is normal. Transmission shifting should return to normal when the transmission oil returns to normal operating temperatures.
.When the transmission oil temperature is extremely cold, the time required to run a system check may increase. During the system check,
the shift lever must stay in the&Pposition. Move the shift lever after turning off the system check display. Also, it is normal to hear clicking
noises during the transmission systems check.
Changing modes
.The higher shift speeds in the&Mposition may result in shift shock and jerkiness when starting or shifting..The quickest shifting in the R mode with the transmission in the&Mposition is available when the engine speed is high. However, the
transmission may shift more slowly when the engine speed is low.
Mechanical Limited Slip
Differential (LSD) If the vehicle accelerates from a stop with the steering wheel turned half a turn in cold temperatures, the inner wheel tire may slip and some
noise or vibration may be heard. This phenomenon occurs because the viscosity of the differential oil becomes thicker and the Limited Slip
Differential (LSD) operates with increasing load. When the steering wheel is returned to the straight ahead position or the differential oil warms
up, the noise and vibration decrease.
GT-R OverviewGTR-29

5-16Starting and driving
partially engaged. Keep the brake
pedal firmly depressed when the
vehicle is stopped. In some circum-
stances the vehicle may not start
moving on its own, however this
does not indicate that there is a
malfunction.
NOTICE
.When the vehicle is stopped on a
hill, do not hold the vehicle in place
by depressing the accelerator pedal.
Doing so may cause the clutch to
overheat and result in transmission
damage. Use the brakes to prevent
the vehicle from moving.
. The GT-R dual clutch transmission is
provided with a dry sump lubrication
system that improves efficiency and
ensures reliability under high g-
force conditions. When oil viscosity
is high at low temperatures, it takes
longer for all components to be
sufficiently lubricated. Thus, when
the transmission temperature is low
(approximately 104 8F (408C) , do not
accelerate rapidly or run the engine faster than 4,000 rpm.
Operating the shift lever
After starting the engine, fully depress the brake
pedal and move the shift lever from the&P
position to the&R,&N,or&A↔&Mposition. Push
the button to shift into the&Por&Rposition. All
other positions can be selected without pushing
the button.

5-40Starting and driving
8. Buy an automated pass for toll roads..Automated passes permit drivers to use
special lanes to maintain cruising speed
through the toll and avoid stopping and
starting.
9. Winter warm up.
.Limit idling time to minimize impact to
fuel economy.
.Vehicles typically need no more than 30
seconds of idling at start-up to effectively
circulate the engine oil before driving.
.Your vehicle will reach its ideal operating
temperature more quickly while driving
versus idling.
10. Keeping your vehicle cool.
.Park your vehicle in a covered parking
area or in the shade whenever possible.
.When entering a hot vehicle, opening the
windows will help to reduce the inside
temperature faster, resulting in reduced
demand on your A/C system.
. Keep your engine tuned up.
. Follow the recommended scheduled main-
tenance.
. Keep the tires inflated to the correct
pressure. Low tire pressure increases tire
wear and lowers fuel economy.
. Keep the wheels in correct alignment.
Improper alignment increases tire wear and
lowers fuel economy.
. Use the recommended viscosity engine oil.

AWD WARNING LIGHT
The AWD warning light is located in the meter.
The AWD warning light comes on when the
ignition switch is pushed to the ON position. It
turns off soon after the engine is started.

Octane rating tips
Using unleaded gasoline with an octane
rating lower than recommended above can
cause persistent, heavy spark knock.
(Spark knock is a metallic rapping noise.)
If severe, this can lead to engine damage.
If you detect a persistent heavy spark
knock even when using gasoline of the
stated octane rating, or if you hear steady
spark knock while holding a steady speed
on level roads, have a GT-R certified
NISSAN dealer correct the condition. Fail-
ure to correct the condition is misuse of
the vehicle, for which NISSAN is not
responsible.
Incorrect ignition timing will result in knocking,
after-run or overheating. This in turn may cause
excessive fuel consumption or damage to the
engine. If any of the above symptoms are
encountered, have your vehicle checked at a
GT-R certified NISSAN dealer or other compe-
tent service facility.
However, now and then you may notice
light spark knock for a short time while
accelerating or driving up hills. This is no
cause for concern, because you get the
greatest fuel benefit when there is light
spark knock for a short time under heavy
engine load.
ENGINE OIL AND OIL FILTER RE-
COMMENDATION
Selecting the correct oil
It is essential to choose the correct grade,
quality, and viscosity engine oil to ensure
satisfactory engine life and performance.
(
“Capacities and recommended fuel/lubri-
cants” page 9-2)
Mobil 1 (0W-40) (100% synthetic) is the factory
fill oil. The VR38 engine with its plasma-sprayed
bores was developed using this oil. NISSAN
cannot ensure proper engine operation and
durability if other 0W-40 synthetic oil is used.
If Mobil 1 (0W-40) is not available, Mobil 1
(10W-40) (100% synthetic) may be used;
however, some performance loss may be
noticed.
NOTICE
Using an engine oil other than that
specified could adversely affect the
engine. See the 2014 NISSAN GT-R
Warranty Information Booklet for de-
tails and exclusions.
Oil additives
NISSAN does not recommend the use of oil
additives. The use of an oil additive is not
necessary when the proper oil type is used and
maintenance intervals are followed.
Oil which may contain foreign matter or has
been previously used should not be used.
Oil viscosity
The engine oil viscosity or thickness changes
with temperature. Because of this, it is important
that the engine oil viscosity be selected based
on the temperatures at which the vehicle will be
operated before the next oil change. Choosing
an oil viscosity other than that recommended
could cause serious engine damage.
Selecting the correct oil filter
Your new vehicle is equipped with a high-quality
genuine NISSAN oil filter. NISSAN recommends
to use the genuine NISSAN oil filter for the
reason described in change intervals.
Change intervals
The oil and oil filter change intervals for your
engine are based on the use of the specified
quality oils and filters. Oil and filter other than the
specified quality, or oil and filter change intervals
longer than recommended could reduce engine

life. Damage to engines caused by improper
maintenance or use of incorrect oil and filter
quality and/or viscosity is not covered by the
NISSAN new vehicle limited warranties.
Your engine was filled with a high quality engine
oil when it was built. You do not have to change
the oil before the first recommended change
interval. Oil and filter change intervals depend
upon how you use your vehicle. Operation under
the following conditions may require more
frequent oil and filter changes.
.repeated short distance driving at cold
outside temperatures
. driving in dusty conditions
. extensive idling
. stop and go “rush hour” traffic
Refer to the “NISSAN Service and Maintenance
Guide” for the maintenance schedule.
AIR CONDITIONING SYSTEM RE-
FRIGERANT AND LUBRICANT RE-
COMMENDATIONS
The air conditioning system in your
NISSAN vehicle must be charged with the
refrigerant HFC-134a (R-134a) and the
lubricant, NISSAN UV Luminous Oil Type
S or the exact equivalents.
NOTICE
The use of any other refrigerant or
lubricant will cause severe damage to
the air conditioning system and will
require the replacement of all air con-
ditioner system components.
The refrigerant HFC-134a (R-134a) in your
NISSAN vehicle will not harm the earth’s ozone
layer. Although this refrigerant does not affect
the earth’s atmosphere, certain governmental
regulations require the recovery and recycling of
any refrigerant during automotive air condition-
ing system service. Your GT-R certified NISSAN
dealer has the trained technicians and equip-
ment needed to recover and recycle your air
conditioning system refrigerant.
Contact a GT-R certified NISSAN dealer when
servicing your air conditioning system.
